Abstract: Surface water quality status and trend of Udaipur’s main lakes namely, Fatehsagar, Pichola lake and Udaisagar has been identify through 10 years freely available online data collected from ENVIS Centre under on Control of Pollution of Water, Air and Noise. Water quality data was collected for the parameters like BOD, DO, pH, Conductivity, NN, Fecal coliform, Total coliform to determine the water pollution level and water treatment requirements. Overall water quality status has been improved during 2016 to 2019 due to waste water treatment plant. Udaisagar is most polluted lake among three lakes. Fecal coliform was suddenly increased in 2018 due to leakage of sewage line near the Pichola Lake. These lakes are interconnected and very useful for drinking, industrial, agricultural and tourism purpose and proper maintenance will be helpful for all dimensional growth of the city. A regression model for BOD was also developed for these lakes. Dependency of Temperature, pH, Dissolved oxygen, NN, Fecal coliform and Total coliform were checked on BOD through SPSS multiple regression analysis. It is found that only Temperature and Total Coliform affects the values of BOD. The variance analysis showed p-values is less than 0.05 and no multicollinearity was diagnosed, with VIF values of < 10.
Keywords: Surface Water, Regression, Water Quality, BOD, Total Coliform, Temperature.
